You must surely be interested in finding out how many people are swingers or, indulge is some sort of group sex activity. Regrettably, it is very difficult to get reliable figures regarding peoples attitudes and activities involving sex with third parties, such as in swinging or group sex (threesomes and orgies).

We have gathered information regarding swinging, group sex, threesomes and orgies in the US, from several web sources which we sumarize in the table below, and for some other countries, which we discuss further down.

The first thing that you will notice in the following table, is the great variability in the data sets, in other words, the figures differ greatly. This may be due to different causes, such as:

Bias due to respondents preferences (more swinger prone people respond to polls than non-swingers), due to the media that conducted the poll (an online swinger contact website will elicit more swinger responses than a ordinary news magazine for average citizens).

Regional or cultural variability. Factors such as political ideology (conservative or liberal), age group preferences, religion, etc. may influence the outcome of a poll and not reflect the exact population mix.

Gender and marital status. Singles may reply differently to married couples and males tend to be more open than women, this can lead the poll to report gender specific results.

For instance, 24% of those living in Vancouver, Canada, had engaged in threesomes, and another 24% (maybe the same respondents?) had indulged in group sex, and of these, over 1/3 to an orgy (9% of all respondents). The 1998 figure for group sex was only 5%, so the trend has been a nearly five fold increase7.

Portland, Oregon, US, just polled intention or willingness to participate in threesomes and orgies5 over 60% of those polled are willing to experiment, but their willingness depends on "you would never see that third person again
